February 18, 2014. Pasternack Enterprises Inc., a manufacturer and global supplier of RF and microwave products, has released all new lines of medium and high power RF loads. These new RF loads (also referred to as RF terminations and dummy loads) are commonly used in military/aerospace, defense, and test-and-measurement applications in order to protect radios and amplifiers under test from excess power.
The new RF terminations from Pasternack come in 25-W, 50-W, and 100-W models and are offered with many connector configurations, including male and female versions of SMA, N, TNC, and 7/16 DIN. The 25-W and 50-W models operate to 18 GHz, with the exception of the 7/16 DIN version, which is rated to 8 GHz. All of the 100-W RF loads operate to 8 GHz. A total of 24 new RF loads are being introduced in this release.
Pasternack’s new medium- and high-power RF loads are manufactured with black anodized aluminum cooling fins for convection cooling. These coaxial terminations require no additional heat sink to dissipate excessive heat during use. Operating temperatures range from -55 to +125°C, making them suitable for a range of environmental conditions in the lab and in the field. The rectangular body can also be hard-mounted using four threaded mounting holes.
“There are many medium- to high-power coaxial termination options available, but very few to 18 GHz,” said Gerry Camacho, vice president of technical marketing at Pasternack. “This new offering of medium- to high-power RF loads provides our customers very broad selections covering wide performance capabilities, allowing them to choose the exact model for the desired application from one supplier.”
The new medium and high power RF loads from Pasternack are in-stock and available now.
